The safety case (SC) is one of the railway industry's most important deliverables for creating confidence in their systems. This is the first book on how to write an SC, based on the standard EN 50129:2003. Experience has shown that preparing and understanding an SC is difficult and time consuming, and as such the book provides insights that enhance the training for writing an SC. The book discusses both "regular" safety cases and agile safety cases, which avoid too much documentation, improve communication between the stakeholders, allow quicker approval of the system, and which are important in the light of rapidly changing technology. In addition, it discusses the necessity of frequently updating software due to market requirements, changes in requirements and increased cyber-security threats. After a general introduction to SCs and agile thinking in chapter 1, chapter 2 describes the majority of the roles that are relevant when developing railway-signaling systems. Next, chapter 3 provides information related to the assessment of signaling systems, to certifications based on IEC 61508 and to the authorization of signaling systems. Chapter 4 then explains how an agile safety plan satisfying the requirements given in EN 50126-1:1999 can be developed, while chapter 5 provides a brief introduction to safety case patterns and notations. Lastly, chapter 6 combines all this and describes how an (agile) SC can be developed and what it should include. To ensure that infrastructure managers, suppliers, consultants and others can take full advantage of the agile mind-set, the book includes concrete examples and presents relevant agile practices. Although the scope of the book is limited to signaling systems, the basic foundations for (agile) SCs are clearly described so that they can also be applied in other cases.

This study, conducted in the capital city of Tanzania - Dar es Salaam, investigated the impact of urban infrastructure interaction on movement and safety on arterial roads. By studying characteristics of urban infrastructure interconnections the effects of urban infrastructure interactions on movement and safety were investigated strategies for ensuring sustainable improvement of movement and safety in the road corridors are recommended. The study employed both quantitative and qualitative research approaches. Data are collected through condition survey, questionnaires, interviews, documentary review, and observation using surveillance cameras. The results that infrastructure within the road corridor exist in inevitable interdependencies, which significantly causes deterioration of each other while impairing movement and safety. Impairment is seriously escalated by mismatches in standards and lack of coordination of operators in planning, designing, installation including operational approaches. It is being suggested that in order to attain sustainable improvement of movement and safety, integrated high performance infrastructure has to be adopted; and for enhancing safety, a model has been developed for planners and engineers for evaluating safety compliance for existing and proposed infrastructure within the road corridors. This book will be of inerest to policy makers, engineers, and researchers in transportation engineering.

This reference book provides traffic safety researchers and practitioners with an international and multi-disciplinary compendium of theoretical and methodological chapters. Together, these chapters discuss the research and application of "Traffic Safety Culture" as an important approach to traffic safety, including the vision of zero traffic fatalities and serious injuries. Traffic crashes are a significant cause of death and debilitating injury worldwide, especially in low- and middle-income countries. Whereas most traditional safety efforts teach safe behavior (education), punish risky behavior (enforcement), or design the environment to minimize crash injury resulting from those behaviors (engineering), there is also the need to understand the culture of our social environments that influence our concern for traffic safety and choice of behaviors. As a result, there is growing interest in the concept of Traffic Safety Culture. However, this concept is relatively new and is not yet supported by a robust theoretical foundation or amassed large body of research. The goal of this book is to create a theoretical foundation and methodological framework for using traffic safety culture, including the discussion of best practices for developing, implementing and evaluating culture-based strategies.

This book proposes the concept of a multi-layer pavement system to fulfill the blast resistance requirement for pavement design. It also presents a damage pattern chart for multi-layer pavement design and rapid repair after blast load. Such a multi-layer system consists of three layers including asphalt concrete (AC) reinforced with Geogrid (GST) at the top, a high-strength concrete (HSC) layer in the middle, and engineered cementitious composites (ECC) at the bottom. A series of large-scale laboratory impact tests were carried out to prove the usefulness of this concept and show its advantages over other conventional pavement system. Furthermore, field blast tests were conducted to show the actual behavior of this multi-layer pavement system subjected to blast load under real-world conditions.

The author includes novel and unusual treatment of the momentum method and coefficient of restitution (which is not yet widespread in accident analysis) and shows how to select the best methods of analysis in a given accident reconstruction.

Will we really soon no longer be sitting behind the wheel of our own car, but will only be taken to our destination by driverless electric taxis? Should cities introduce car sharing? What role will electric scooters, cable cars or man-carrying drones play in the mobility systems of major cities? This book finally explains in a generally understandable way what is really behind buzzwords such as electric mobility, autonomous driving, digitalization and mobility services such as car sharing or ride-hailing, how far advanced these technologies are today, and above all in what relationships and dependencies they are to each other. In addition to the technical aspects, the legislative and social trends are also considered, which are important framework conditions that will have a decisive influence on the mobility of the future. From the contents - Mobility needs: Who wants to go where, when and why - and how will this change in the future? - Technological trends: electromobility, digitalization, autonomous driving - what will the vehicles of the future be capable of? - Car sharing, ride-hailing, e-scooters or public transport: What alternatives to the private car will there be in the future? - Politics and society: How will the framework conditions for mobility develop in the future? - Mobility in transition: What should we do to prepare for the future?

There is considerable uncertainty about what level of traffic loading bridges should be designed for. Codes specify notional load models, generally to represent extreme levels of normal traffic, but these are often crude and have inconsistent levels of safety for different load effects. Over the past few decades, increasing quantities of reliable truck weight data has become available and it is now possible to calculate appropriate levels of bridge traffic loading, both for specific bridges and for a road network. Bridge Traffic Loading brings together experts from all over the world to deliver not just the state-of-the-art of vertical loading, but also to provide recommendations of best-practice for all the major challenges in the field - short-span, single and multi-lane bridge loading, dynamic allowance and long-span bridges. It reviews issues that continue to be debated, such as which statistical distribution is most appropriate, whether free-flowing or congested traffic governs and dealing with future traffic growth. Specialist consultants and bridge owners should find this invaluable, as will regulators.

Roadwork: Theory and Practice, now in its sixth edition, gives the essential information needed by every road worker, highway technician, incorporated, graduate or chartered engineer, not only by explaining the theory of road construction and its associated activities, but by illustrating its application with practical working methods that are in use in everyday engineering practice. As such, it successfully bridges the gap so often found between civil engineering theory and the day-to-day work of a highways engineer. The authors have drawn from a lifetime of experience in the construction industry and included current design and construction practices.
